What least value should be given to so that the number 8456 4107 is divisible by 3?

Answer:-We should know the divisibility rule of 3.what does it say?.

Divisibility rule of 3 – Sum of the digits must be divisible by 3.

=8+4+5+6+4+1+0+7

=35.

which is not divisible by 3.

so we can not put * as 0.

but we can take * as 1.

If we will put * as 1 the sum would be =8+4+5+6+1+4+1+0+7

=36(again 3+6=9).

which is divisible by 3.

Hence 1 is the least value that can give to * so that the number
